Article: Bullpen Competition Gets Crowded

If this is true - and I'm not conceding it is - then park factor is mostly useless.

 

The only way to properly calculate park factor is to use a wide range of seasons and compare them to other parks during the same year.

 

For example, one would need to treat the seven years of Target Field nearly equally and Target Field can't be isolated; ie. 2010 Target Field needs to be offset by factors such as "how did the 2010 Indians play in Yankee Stadium, how did the 2010 Rangers play in Angel Stadium, etc." and equalize those numbers against how those same teams performed in 2010 Target Field.

 

That's the only way I can think of to minimize home team influence on their own stadium.

 

OK we agree.

I've noticed that trend over the past couple of years. After being an extreme pitcher's park in 2010, it seems Target Field has slowly evolved into a slightly hitter-friendly ballpark.

 

The only reasonable explanation is that the concrete has finally cured.

Also the center field trees. Those supressed 20-30 homers easily.
